Throwback Thursday: Heart Rate Edition
Back in college I took a course called 2.671: "Go Forth and Measure". It was all about designing experiments and how to measure results. My culminating project was one I got to create and refine from start to finish. Being a gun girl, I opted to measure the effect of shooting experience on heart rate during rifle practice.
This research was not groundbreaking by any means, but it was a ton of fun to do! My college rifle teammates served as willing "lab rats".
Here were my conclusions*:
- Shooters experienced oscillatory heart rate over time, increasing and decreasing periodically around a mean match heart rate.
Shooters tended to fire their shots close to the local minimum heart rate.
A comparison of the shooters in this study resulted in an "experience factor" of Efactor= 1.7%/year ± 1%/year with 95% certainty gain in percentage of shots fired below mean measured heart rate.
Consistency in the time between shots also increased with years of training experience - shooters with more experience got into a rhythm!
* This was a small sample size, so take these results with a grain of salt!
I love it when my passions for precision shooting and engineering collide!
